NEEDER ATTACHMENT FOR l-IARROWS.

Application filed. Geteber 13, 1927. Serial 1-10. 225st? This invention reletes to e \reeder nttzrcln ment for her-rows.

it is generally aimed to provide an exceedingly siinple, inexpensive, compact r nd generellv ellicient attachment of this character and purziculu one wherein theuttncinnent may be us ll both to Width end as to the depth of the weeder blade, and to provide {LY-CU" *"ariution wherein such blade will renniin ut the szune depth end he urged to that depth after adjustment, rind regardless-1 ol' the angle of adjustment oi the hzirrow teed.

Various additional objects and advantages will becorne apparent iron at considerttionot the description tollewin taken in connection with accompanying drawings illust fitting on operative embodiment.

1 v t one end is I zeta posidesigneees ll hurl-ow oi the drug which is to be taken as con vent1cun.... type shown in the torn] o'l' F1 gures 1 lo 4- has 1"" tootl1ed:-1uppoiting burs, round or tubular in term as shown at 1Q, the teeth being oesignuted 11 uni, ad ustab e to serious angles. I

in carrying out my invention tivo ln'uchets 18, generally of lrshape are used. Such brackets may be inetnllic burs hztvii'ig one 2nd flattened at 14: and secured to one o the Jan's by securing them to shrinks 15 of some of the teeth 11 or by means of other siiiitnble fusteninns. The opposite ends of each bar 18 extends upwardly as at 16 and is provided with a series of openings 17.

A \veeder lr: fine is provided which consists of side herons 1'?" which 211", joined intermediate their ends by means of links 18 which overlap end are provided. with elon red slots 19 and ncconnnodate belts or other lidstenings 2 show- 520, so that thewidth of the frame may be ad justcd according to the hsrrow or the Work. '1. he renr ends 01 the bars 1'? are arched or curved downwardly as at 21 and at their lowor ends support it Wonder blade 22 of any preferred form, In order that the blmle inuy ncconnnodute the ud'justinent referred to, the some is provided with elongated slots at 255 through which securing bolts 21-, carried by the endsot the nrelieu 251, are secured.

The frame of the Weeder also consists of side burs u: at having upstanding terininnls 46 at their rear ends provided with :1 series 01? ipenings 21' therein. llolts 528 secure the links is to the burs 17 and as well are adapted to be selectively secured in the openings so as to vary the heigl'et oi the \ve-cder blade Adj scent the Tl Ol'WM'd ends, the burs 17 by moons of bolts 28 are adopted to he secure: adjustnbly us to he i ht to upstanding urine 29 forming part (it the wonder frame, such arms huving u series of openings 30 to selectively zu'coinn'iodute the bolts 28.

ii. main shaft, preferably square as shown at 81 provided with journals or sleeves 32 sliduble along the some and held ugziinst displacement by means of hinding screws 33 Whien may engage the bar 31. Such sleeves 32 While they slide longitudinally oi the bar 31 do not turn independently thereof and rigidly attached to the sleeves are the side burs and the arms 29, such sleeves being journnlcd in the brackets 13.

in order to hold the rear end or Weeder blnde at the proper depth in the ground and purticulurly when the burrow teeth are rid justed ct diilerent anglers relatively strong contractile springs, 35 are provided. Such springs may engage hooks 136 depending from the brackets 13 at one end, and eye bolts 37 carried by the links 18.

In order to operate or turn the shaft 31, and thin; elevate the Weeder device us a unit, in order to (luiup i that is move the some from the posi ion oi Figure 2 to that of Figure 3 en upstanding ZU'lIl 353 is attached to the shaft 31. This nrin may be rigid on a spool or sleeve 39 end the latter slidehle along the shaft 31. but normally held ogei nst movement thereon by a, binding screw 10. This adjustmentennbles the arm 38 to be centered according to ndjustru out or" the device as to Width. The iii-in 38 may be operated in any suitable manner in order to raise and lower the frame and blade 22 and for instance may have an operating cable ll attached to its upper end and be guided over a pulley or other means 42 anchored on the harrow the device being ele vated upon drawing on the cable 41 and lowered by its own weight or gravity when the tension on such cable is released.

The side arms or bars 17 may be raised to keep the blade 22 elevated when not in use and so maintained by pins 43 applied in openings 17.

The form of harrow to which the device is shown attached in Figures 1 to 4 uses a round bar. In the case of a harrow utilizing a U-ba-r as in Figure 5, a bracket is used to function similarly to that at 13. The harrow bar is shown at 51 and a bracket 52 straddles the same and hasa downwardly extending terminal 53 of the bracket 50 passed through openings inits end and held against accidental detachment by means of a pin 54 passed through an opening in the part 53, or by any otherlsuitable means.

- In Figure 6, still another form of bar for the harrow is shown. In this instance it is recta-ngularand designated 60. The bracket 61 functioning similarly to those at 10 and 50 and secured thereto by means of spikes or any other approved fastenings 62 similarly to the form of Figure 1.-

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention 1. A weeder device of the class described comprising attaching brackets, a shaft journaledtherein, side arms, arms rising from said, shaft, side arms extending from the shaft, means securing the side arms to the second mentioned arms and side arms, and a weeder member carried by the side arms.

2. A weeder device of the class described comprising attaching bracket-s, a shaft journaled therein, side arms, arms rising from said shaft, side arms extending from the shaft, means securing the side arms to the second mentioned arms and side arms, a weeder member carried by the side arms, and means for varying the posit-ion of the side arms relatively to each other and their connection to the weeder member.

- 3. A weeder of the class described comprisingattaching brackets, a square shaft, sleeves on said shaft ourna-led in said brackets, said sleeves being slidablc along the shaft and having means to secure them a iinst sliding movement relatively to the shaft, side arms, means adjustably securing the side arms for movement relatively to each other, a weederv member carried by the side arms, upstanding a 'ms rigid with the sleeves. auxiliary side arms rigid with the sleeves, and means adjustably securingthe side arms to the upstanding arms and auxiliary side arms.

4. A weeder of the class described comprising attaching brackets, a. square shaft, sleeves on said shaft ournaled in said brackets, said sleeves being slidable along the shaft and having means to secure them a gainst sliding movement relatively to the shaft, side arms, means adjust-ably securing the side arms for movement relatively to each other, a weeder member carried by the side arms, upstanding arms rigid with the sleeves, auxiliary side arms rigid with the sleeves, and means adjustably securing the side arms to the upstanding arms and auxiliaiy side arms, rosilient means connected to the brackets, links adjustably connecting the side arms, and said resilient means also being connected to the links, and an operating arm extending from the square shaft.

An attaclnnent of the class described con'lprising attaching brackets having upstanding terminals provided with oi'ienings, a shaft having sleeves jonrnaled in said brackets, upstanding arms rigid with said sleeves, auxiliary side arms rigid with said sleeves, side arms adjnstably connected to said upstanding arms and auxiliary side arms and provided with downwardly extending terminals, a weeder blade having elongated slots. means passing through said terminals and said elongated slots to secure the blade to the side arms, openings in said brackets being adapted to accommodate supporting elements to maintain the side arms in elevated position, an operating arm extending from the shaft, links extending from the side arms, said links overlapping and having elongated slots. tastening elements accon'lmodatcd in said slots, coil springs attached to said links, and books on the brackets to which the coil springs are attached.

In testimony whereof I aliix my signature.
